T0 aZZ whom it may concern Be it known that I, PRINCE JosEPH MARIE JEAN ARMAND PIGNATELLI DARAGON, residing at Hotel de Bordeaux, Tours, Department Indre et Loire, France, have invented certain new and useful Improvements in Ventilators for Railway-Carriages, Tramway Cars, and other Vehicles; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention consists of a ventilator for purifying and renewing the air in railway and tramway carriages or other vehicles in motion, and belongs to that class of ventilating apparatus in which the air which enters the vehiole is first caused to pass over water contained in a suitable receptacle, by which dust and other impurities are removed.

The invention consists more particularly in the construction hereinafter set forth also, in the arrangement of means for preventing undue agitation of the water in the reservoir, due to the motion of the vehicle; also, in the arrangement of means for collecting water 'entrained into the air-delivery pipe by the aircurrent, and for returning said water into the reservoir, thus preventing its entry into the vehicle; also, in the counter-weighted valve, whereby the quantity of air entering the vehicle may be regulated; also, in the devices for securing the air-receiving funnel in either of two positions, as desired. I

In the accompanying drawings, Figure 1 is a side elevation of the apparatus. Fig. 2 is a plan view, showing certain portions in horizontal section. Fig. 3 is a vertical section on the line as x of Figs. 2 and 4.. Fig. 4 is a section 011 the line 3/ 9/ of Figs. 2 and 3. Fig. 5 is a vertical sectional view, showing in .detail the method here adopted of attaching the airreceiving pipe to'the box.

Similar letters of reference indicate like parts.

The device is'intended to be arranged upon the roof of a railway-car, a portion of which roof is shown at A, Figs. 1, 2, and 3.

B is the air-receiving pipe, the outer end of which is of flared or funnel form, and the inner end is bent downward to enter the box 0. The enlarged open end of the pipe B stands about parallel with the roof of the car, and the opening is intended to face the direction in which the car is moving, so that a current of air will thus be forced into the pipe B, and thence pass to the box 0. The box 0 is partially filled with water. In the interior of the box 0 is arranged a fixed partition, D, which bisects the inner opening of the pipe 13. This partition extends only a part of the way across the box. I also place in said box aframe divided by a series of partitions, E. This frame stands across the box and transversely to the partition 1). It may be easily removed from the box by opening the door F on the upper side of said box. The object of the fixed partition D and of the removable frames and'partitions E is to prevent the water in the box from being too violently agitated and dashed into the air-tubes by the motion of the car.

Rising from the box 0, as shown in Fig. 3, is the air-delivery tube G, which is arched, bends downward, passes through the roof of the car, into which it opens at H, Fig. 4. At about its middle portion this arch-tube G is provided with an angular enlargement, I, which enlargement, by means of a small pipe,

J, communicates with the interior of the box O. The object of this enlargement I is to collect any water which may be carried up into the tube G by the air-blast and prevent the same from passing down into the car. The water so collected is conducted back to the box 0 by the pipe J. In the delivery-orifice II, and at about its center, I provide a deflecting cone, K, which may be supported by arms extending from the'inner periphery of the pipe G, or any other suitable means; and I also flare said pipe G at its outlet, so-that the escaping air-current may be caused to diverge, and thus be better distributed in the car. In the pipe G, and near the outlet H, I place a pivoted valve or damper, L, having a rectangular upper projection, M, so that'said valve is thus counterweighted and normally held shut. To the opposite side of the valve I attach a cord, N, which may pass down through the cone K, and by means of which cord the valve may be conveniently opened more or less, and, by securing the end of said cord within the car, held in any desired position.

Various means may be adopted for attaching the pipe B to the box C, so that the outer funnel end of said pipe B may be turned in either direction, as indicated by dotted lines in Figs. 1 and 2. The means which I here show is constructed as follows: A circular opening is made in the top of the box 0. In said opening I insert a sleeve, 0, Fig. 5, having a flange, P, which rests on top of the box. By means of this flange the sleeve may be secured to the box by rivets, bolts, solder, or any other convenient way. On the pipe B, I

attach a flanged ring, Q, the horizontal por-- tion of which passes beneath clips B, secured in any suitable way to the flange 1?. The ring -Q,, which thus supports the pipe B, is free to rotate beneath said clips It.

In order to secure the pipe B turned in either direction parallel to the roof of the car, I secure metal eyes S S on each side of the pipe B, and I fasten corresponding eyes, T T, on one side of the pipe G. I also provide a pin, U, adapted to enter said eyes, which I secure from loss by means of a chain or cord, V, connecting said pin to the pipe G. It will be seen from Fig. 1 that when the pipeB is turned in one direction the eyes S and T coincide,

and when the pin U is inserted through said eyes the pipe is thus secured in place. Similarly, when the pipe B is turned in the opposite direction, the eyes S and T coincide, and

the pin U, inserted insaid eyes, holds the pipe in that posit-ion.

The cock IV is connected to the box 0 at about the proper water-level, so that by opening said eocl; the fact that the water has reached the proper height can easily be determined.

An outlet-pipe for drawing oft the water when desired, and which is closed by a screweap, is shown at X.

The lid F of the box 0 is provided with a suitable liasp 01' catch forholdingitshnt. The

direction of the aincnrrents passing into the apparatus is indicated by the arrows in Fig. 3.

The operation of the apparatus is as follows: The enlarged end of the pipe B being turned in the direction in which the train is running, air enters into said pipe, and, passing through the same, comes in cont-act with the water in box 0, by which it is purified from dust, cinders, &c. The air-current then passes out through the pipe G to the interior of the car.

I am aware that ventilating devices for railway cars have hitherto been constructed wherein the air received by a pipe with an enlarged. opening is brought into contact with water in a suitable receptacle, and after being thus purified it is led into the car. This construction I do not broadly claim.

I claim as my invention- 1. In a railway-car ventilator substantially as set forth, a water-receptacle provided with a removable frame containing a series of partitions, E, and resting upon the bottom of said water-receptacle, substantially as described.

2. In a railway-car ventilator, the combination of an air-receiving pipe and a water reservoir or receptacle with an air-delivery pipe provided with an enlargement and a tube connecting said enlargement and the water-reservoir, substantially as described.

3. The combination, as herein set forth, of the air-pipe B and water-receptacle O, with flanged sleeve 0, flanged ring Q, and clips R, substantially as described.

4. In a railway-car ventilator, an air-delivcry-pipe having a flared outlet, in combination with an air-diffusing cone suitably sup ported in the center of the outlet-orifice, substantially as described.

In combination, the pipe B, the eyes S and S, the pipe G, the eyes T and T, and the pin U, substantially as described.

In witness whereof I have hereunto set my hand this 22d day of September, A. I). 1882.
